A Belated Tree

- -in honour of Joe Tree , founder of this amazing site. Sorry , two days later than  the official Joe Tree Day. Does anyone know what is significant about 1 March?  

According to Wikipedia   " To date, 'Blippers' in over 170 countries worldwide have posted 3.4 million photos with close to 22 million shared comments on the site. Each photo on Blipfoto represents a single day in someone's life - so there are almost 3.5m individual days saved to date."

THANK YOU JOE.  You have enriched my life
